A pneumatic nebulizer that produces a high volume of aerosols for inhalent delivery of medications and other constituencies. High pressure gas formed into a gas jet is passed through a thin choked region of fluid that is entrailed and impinged upon an aerosol amplifier which creates a spray whose aerosol components are directed up through vents to an aerosol outlet for delivery. Larger-sized liquid particles are caused to pool up in a region surrounding the aerosol amplifer and then drip down back into the liquid medication reservoir.

A system and method for generating an oxygen enriched aqueous solution for therapeutic application includes a diffuser comprising a first diffusing member having a surface incorporating surface disturbances, and a second diffusing member positioned relative to the first diffusing member to form a channel through which an aqueous solution and oxygen gas may flow. A reservoir containing the aqueous solution is connected to a pump that draws the aqueous solution from the reservoir and inputs the aqueous solution into the diffuser. The aqueous solution is moved through the channel relative to the surface disturbances to create cavitation in the aqueous solution to diffuse the oxygen gas into the aqueous solution to produce an oxygen enriched aqueous solution.

Disclosed is a unique fuel and air premixing system for a gas turbine catalytic combustion system.

Features have been incorporated in the system to make it resistant to flameholding.

A heat and humidity exchanger comprises a pleated membrane cartridge disposed in a housing. The cartridge comprises a pleated water-permeable membrane via which heat and humidity can be transferred between two fluid streams. A flow field element is disposed within some or all of the folds of the pleated membrane, for directing the stream over the inner surfaces of the folds. The flow field path defined by the flow field element enhances flow distribution across one or both membrane surfaces, controlling the relative flow paths of the two streams on opposite sides of the membrane and reducing the pressure drop across the heat and humidity exchanger. The flow field elements provide improved water transfer and allow for a more compact device. The flow field elements can also assist in supporting the pleated membrane and controlling the pleat spacing within the pleated membrane cartridge. The heat and humidity exchanger is particularly suitable for fuel cell and energy recovery ventilator (ERV) applications.

A process and system for producing hydrocarbon compounds or fuels that recycle products of hydrocarbon compound combustion—carbon dioxide or carbon monoxide, or both, and water. The energy for recycling is electricity derived from preferably not fossil based fuels, like from nuclear fuels or from renewable energy. The process comprises electrolysing water, and then using hydrogen to reduce externally supplied carbon dioxide to carbon monoxide, then using so produced carbon monoxide together with any externally supplied carbon monoxide and hydrogen in Fischer-Tropsch reactors, with upstream upgrading to desired specification fuels—for example, gasoline, jet fuel, kerosene, diesel fuel, and others. Energy released in some of these processes is used by other processes. Using adiabatic temperature changes and isothermal pressure changes for gas processing and separation, large amounts of required energy are internally recycled using electric and heat distribution lines. Phase conversion of working fluid is used in heat distribution lines for increased energy efficiency. The resulting use of electric energy is less than 1.4 times the amount of the high heating value of combustion of so produced hydrocarbon compounds when carbon dioxide is converted to carbon monoxide in the invention, and less than 0.84 when carbon monoxide is the source.

A system is disclosed that incorporates a generator for generating a liquid coolant. This invention provides a self-contained water (or similar liquid coolant) chilling system of suitable capacity to cool small to medium size structures, such as private residences and manufactured homes. The system utilizes an arrangement of heat-exchanging panels to pre-condition an ambient temperature air-stream, prior to passage through a pump-driven coolant spray. The system also provides several sub-systems for automatic coolant monitoring, chemical addition and periodic coolant replacement.

A high performance liquid chromatography system employs a nebulizer with a flow restriction at the exit of its mixing chamber to produce finer droplets, and an adjustable impactor for increased control over droplet sizes. Downstream of the mixing chamber, the nebulizer can incorporate tubing that is permeable to the sample liquid, to promote aerosol drying through perevaporation. A condensation particle counter downstream of the nebulizer uses water as the working medium, and is adjustable to control threshold nucleation sizes and droplet growth rates. A particle size selector employing diffusion, electrostatic attraction or selection based on electrical mobility, is advantageously positioned between the nebulizer and the CPC.

Waste gas and water are sucked downward through a set of turbulence inducing baffles 28. The remaining waste gas is sucked out though exhaust tube 30, using vent fan 31, and vented to the atmosphere.
